Tracking Device Viewed Position Irregularity Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tracking technologies may inadvertently track subjects unintended by the user, especially when multiple subjects are moving in a video, leading to loss of focus on the intended target.
Innovation Solution
A tracking device and method that acquires the viewed position of a user and controls the tracking unit based on the degree of irregularity of the viewed position, using a line-of-sight acquisition unit and image processing to determine if the user is still focusing on the intended subject, and adjusting the tracking accordingly.

Engineering Contradiction Analysis
1Speed
If tracking control is performed based on viewed position alone, then tracking responsiveness is improved, but tracking accuracy deteriorates when user loses sight of target
Solution Approach 1:
The tracking control dynamically adjusts between two modes: when the viewed position changes regularly, the system tracks based on viewed position for responsiveness; when irregularity is detected, it switches to tracking based on subject position for accuracy. This dynamic adaptation resolves the contradiction between responsiveness and accuracy.
Solution Approach 2:
The system calculates the degree of irregularity of viewed position changes as feedback to determine which tracking mode to use. This feedback mechanism allows the system to automatically switch between tracking based on viewed position and tracking based on subject position, ensuring both responsiveness and accuracy are maintained under different conditions.

If tracking switches to subject closer to viewed position, then tracking responsiveness is improved, but tracking reliability deteriorates when user did not intend to focus
Solution Approach 1:
The system dynamically determines tracking mode based on the calculated degree of irregularity. When irregularity is low, it switches to viewed-position-based tracking for responsiveness; when irregularity is high, it maintains subject-position-based tracking for reliability. This dynamic adjustment prevents unintended tracking switches.
Solution Approach 2:
The degree of irregularity calculation provides feedback about user viewing behavior, enabling the system to distinguish between intentional tracking adjustments and unintentional loss of sight. This feedback prevents false switching to unintended subjects by recognizing patterns of genuine user intent versus accidental viewing shifts.

AI summary
A tracking device comprising at least one memory and at least one processor which function as: an acquisition unit configured to acquire a viewed position, which is a position on a display viewed by a user; a tracking unit configured to track an object displayed on the display; and a control unit configured to perform control processing to control the tracking unit based on a degree of irregularity of a change of the viewed position.
